Abstract

L'invention concerne un procédé permettant d'échanger de manière sûre les informations se rapportant à l'automatisation de la conception en électronique. Ce procédé permet de sécuriser les informations considérées comme sensibles, ou méritant d'être protégées pour d'autres raisons, par des procédés tels que chiffrement, obscurcissement et d'autres mesures de sécurité. Il permet de traiter les informations tout en évitant qu'une partie au moins des informations sensibles ne soient divulguées. Dans un exemple, une annotation sélective des fichiers de règles associés à la fabricabilité de circuits intégrés permet d'indiquer les parties devant être soumises à une protection. Un outil de chiffrement peut être utilisé pour sécuriser les informations se rapportant à l'automatisation de la conception en électronique, et un outil d'automatisation de la conception en électronique peut ensuite déverrouiller et utiliser les informations sécurisées sans divulguer ces dernières. Dans un aspect, cet accès ou cette utilisation sécurisée des informations peut être soumise à une ou plusieurs conditions devant être remplies (p. ex. une période de temps ou un nombre d'utilisations ou d'accès). L'outil peut par exemple être un outil de vérification physique permettant de vérifier si l'une ou l'autre des topologies de circuits intégrés risque de violer une ou plusieurs des règles sécurisées.
